Belden microphone cable is used for connecting low level microphones or musical instruments. Key properties of microphone (MIC) cable are ruggedness, flexibility, flex life and interference immunity.Cable construction utilizes a 4 conductor configuration. Quad MIC cables are connected by attaching the two white conductors to one pin and two blue conductors to the other pin in a balanced-line XLR type connector. Besides the common-mode rejection of a standard balanced line, this gives common-mode rejection at each pin, greatly reducing noise and interference.

All Belden microphone cables utilize only HIGH CONDUCTIVITY copper produced by a process called ELECTROLYTIC TOUGH PITCH. This refining process produces a copper conductor that is 99.95% pure copper resulting in HIGH CONDUCTIVITY per ASTM B115. The high purity obtained from ETP copper results in microphone cable performance that is comparable to that of oxygen free copper cables.
